我是 JFreechart 的新手，我已经生成了一个条形图。酒吧里有一条闪亮的线。我想知道是否有可能摆脱酒吧中的这条线。我希望酒吧具有哑光效果。我附上了我生成的条形图的图像。任何指针都会有很大帮助。
提前致谢。

public JFreeChart createBarChart(CategoryDataset dataset) {
// TODO Auto-generated method stub
String unter_title="No of counts";
JFreeChart jfreechart = ChartFactory.createBarChart(title, unter_title, "frequencies", dataset, PlotOrientation.VERTICAL, true, true, false);
String text="Test Start Time: "+(new Date(test.getStart_utc_timestamp()).toString()+" "+"Test End Time: "+new Date(test.getEnd_utc_timestamp()));
jfreechart.addSubtitle(new TextTitle(text, new Font("Dialog", 3, 10)));
CategoryPlot categoryplot = (CategoryPlot)jfreechart.getPlot();
categoryplot.setDomainGridlinesVisible(true);
categoryplot.setRangePannable(true);
NumberAxis numberaxis = (NumberAxis)categoryplot.getRangeAxis();
numberaxis.setNumberFormatOverride(NumberFormat.getPercentInstance());
numberaxis.setUpperMargin(0.10000000000000001D);
BarRenderer barrenderer = (BarRenderer)categoryplot.getRenderer();
barrenderer.setDrawBarOutline(false);
barrenderer.setSeriesPaint(0, Color.DARK_GRAY);
barrenderer.setMaximumBarWidth(0.0500000000000000001D);
barrenderer.setLegendItemToolTipGenerator(new StandardCategorySeriesLabelGenerator("Tooltip: {0}"));
CategoryAxis categoryaxis = categoryplot.getDomainAxis();
return jfreechart;
